SUBJECT: CR-420 ANTI-STATIC

PAPER

SETUP

Reports from the field have suggested that some paper jams and

circuit board damage is being caused by static build up, possibly

due to incorrect installation or non-use of the paper rack.

In order to prevent static build up it is essential that certain

parts of the printer are properly installed. Moreover, the A/C

outlet must be the 3 prong type and grounded. The paper rack

provides a discharge path for the static charge that accumulates on

the paper. If the rack is not installed and grounded properly, the

static build up could cause problems. Page 2 shows the parts that

need to be connected to have a complete ground path for static

build up. Use the part numbers listed below if there is a need for

replacement parts.

The "static ground brushes", which are not shown, are located on

Q;k!nner

side of the "printer cover". They connect to the "paper

through the "rack mounting units", on either side of the

upper case. The "paper rack" is then grounded to the "lower case"

through the "ground wire" at junction "A".
